An escalation of violence in South Sudan since July 2016 has lead to a large population movement into the north of neighboring Uganda. An estimated rate of between 2,000 and 3,000 displaced persons cross the border into Uganda each day. In a rapidly developing situation such as this, it is vital that accurate and up-to-date mapping information is available to allow the ERU to respond more effectively and efficiently.

The maps that you create in this task will enable sanitation facilities - including latrines, hand washing points and hygiene promotion activities - to be effectively provisioned for the people living there.

For this task, mappers are being asked to map buildings and the road network across the area of the camp.

The imagery will show buildings as a mixture of ‘formal’ constructions, tents and other structures; the road network will also be a mixture of ‘formal’ tracks (laid out in a grid system), and less paths.

To help you in your mapping, please look at these images. The photos shows examples of what some of the structures and roads may look like.

Shelters

In the ID editor: label the area as “Building”, then correct for right angles with the “S” key

In JOSM: from the Tags/Memberships window, click “Add” and use the tag “building=yes”; then correct for right angles using the “Q” key

Road network

Roads should be identified with respect to their economic and social role, not in terms of their visibility/viability. The best way to approach this is to use the existing road network and its connections to towns and villages.

Inside of the camp please use highway=residential (with the exception of major roads) (in ID : choose "Residential road")

Outside of the camp please use highway=unclassified : or "Minor/Unclassified Road" : for those roads connecting villages and hamlets

You should not have to use :

highway=primary, highway=secondary or highway=tertiary : these are the main roads that connect towns. You shouldn’t need to create them for this project.

highway=track (roads or paths which connect fields only) and “highway=path”(roads too narrow for a 4-wheel drive vehicle to pass)

The most important thing is to maintain consistency in the network. Every road should connect to another of greater importance and not to isolated roads.

Imagery details:

This imagery is from DigitalGlobe’s WorldView 3. The imagery has been orthorectified for terrain corrected geographic precision. Additionally, the imagery has been contrast stretched using a custom stretch and processed into a Tiled Map Service (TMS) for performance. The image you are using was taken on 10 April 2017.
